The Mallet

Malj

Sinopse

In a futuristic, antiseptic food factory, workers select healthy chicks, while the rejects are carried along a conveyor belt until they are crushed by a mallet and drop into a garbage bin. A single black chick appears and before the mallet strikes, he rebels.

The IMDB synopsis is misleading: this isn't "futuristic". This is yesterday and today. Disturbing and real, all the ills of mankind are condensed into the plight of the little black chick.
